Lamborghini has released full details of its highly anticipated Aventador Roadster.

At the heart of the Aventador Roadster is the same V12 6.5-liter normally-aspirated engine featuring stop/start system, cylinder deactivation, and connected to a 7-speed automatic transmission. With the roof up, it needs three seconds to complete the 0-62 mph (0-100 km/h) on its way to a top speed of 217 mph (349 km/h).

Because of the new roof, the car?s rear pillars had to be redesigned to provide additional strength when driving without the roof. These also provide extra ventilation to the power unit and offer more rollover protection.

Lamborghini?s engineers have installed a powered rear windscreen that can control airflow over the vehicle, as well as the level of noise coming from the engine that passengers can hear while driving with the roof down. On top of the front windscreen is a wind deflector that promises to ?deliver almost complete calm? in the cabin when the roof is removed.

In addition, the engine cover now features a ?spinal column? with two lines of hexagonal windows, while the scissor doors have a chamfered edge for the frameless windows, providing a tight finish into the carbon fiber roof.

Some of the Roadster-exclusive features include 20- and 21-inch (front/rear) alloys that lower the vehicle?s weight by 10 kg (22 pounds), along with a bespoke two-tone finish. The car seen in these official photos is wearing an Azzuro Thetis paintjob, a throwback to the paint used for the 1968 Miura Roadster.

The 2013 Lamborghini Aventador Roadster will go on sale next summer at a starting price of 300,000 EUR before taxes.
